Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 1 + 2\cdot 17 + 3\cdot 17^{2} + 3\cdot 17^{3} + 12\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 5 + 2\cdot 17 + 8\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 6 + 14\cdot 17 + 9\cdot 17^{2} + 6\cdot 17^{3} + 12\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 11 + 8\cdot 17 + 5\cdot 17^{2} + 9\cdot 17^{3} + 14\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 12 + 6\cdot 17 + 15\cdot 17^{2} + 14\cdot 17^{3} + 3\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
